Boost.Range

Portability

A huge effort has been made to port the library to as many compilers as possible.

Full support for built-in arrays require that the compiler supports class
template partial specialization. For non-conforming compilers there might be a
chance that it works anyway thanks to workarounds in the type traits library.

Notice also that some compilers cannot do function template ordering properly.
In that case one must rely of range_result_iterator
and a single function definition instead of overloaded versions for const and
non-const arguments.
So if one cares about old compilers, one should not pass rvalues to the
functions.
